[QUERY] Have custom workflow interface with other Slack apps

[benjrich-jasper]

Question
Are we to have our custom workflows interface with other installed slack apps?
e.g. have a workflow step essentially send a slash command to another app allowing us to trigger a workflow in that app.

Context
I've looked around in the docs and haven't found anything. Don't even know where to start to add this to our current app.

Environment
N/A

Hi @benjrich-jasper! Currently, I don't believe it's possible for custom workflows to interact directly with existing apps (unless, of course, your workflow sent a message that your existing app listened for and took action after, or something similar. Probably not what you're looking for).

To be clear, are both apps you're referring to built with the Deno SDK, or is one app (the current one?) built with Bolt (or another SDK)? More information the better; it'll help us understand what support is missing and sought after.

Thanks for the quick reply! Our current app is built on the Deno SDK, I'm not sure about the other app, Linear

The Linear app has all the functionality we need for keeping both the slack thread and the linear issue synced up, but not all the pre-processing that we're doing in our internal app built on the Deno SDK

It's a neat idea, and makes sense to me, especially as a means to 'bridge' the automation platform with the old-school platform. I've raised this internally to solicit ideas / feedback.

I just saw the January Admin email, and found a really exciting update! Looks like we can now create workflows in Slack that can connect w/ select services.
Are we able to do this via the deno sdk? Or is this only available via the Workflow Builder in Slack?

Yes! While still early and in active development, there are essentially a set of pre-built custom functions you can use in your coded workflows for a variety of third party services available. Check out GitHub.com/slackapi/deno-slack-hub for the details.

Amazing!!! Thank you!
One thing that is still missing, is a way to link a slack thread with a Linear issue. Linear has this implemented in their Slack app, and we've got a custom workflow that's doing this for us, but in a very janky way. We'd love the ability to utilize this feature in the Linear slack app. 🙏

Noted! I have raised your comment with our connectors team; if there's any development on that end, I'll update this issue.
